2, power cable
The main features of this type of product are: extrusion (winding) insulation on the outer conductor, such as overhead insulated cable, or stranding (corresponding to the phase, neutral and ground of the power system), such as overhead insulated cables with two cores or more , or add a jacket layer, such as plastic / rubber sheathed wire and cable. The main process technologies include drawing, stranding, insulation extrusion (winding), cable-forming, armoring, and sheath extrusion. The different process combinations of various products have certain differences.
The products are mainly used for transmission of strong electric energy in the transmission, distribution, transmission, transformation and power supply lines. The current passing through is large (tens of amps to several thousand amps) and the voltage is high (220V to 500kV and above).

4, communication cable and fiber (a brief introduction)
With the rapid development of the communication industry in the past two decades, the products have also experienced phenomenal development speed. From the simple telephone telegraph cable in the past to thousands of pairs of cable, coaxial cable, optical cable, data cable, and even a combination of communication cables.
The structure size of such products is usually small and uniform, and the manufacturing precision is high.

5, electromagnetic wire (winding wire)
Mainly used in various motors, instruments and so on
The derivative/new products of wire and cable are mainly due to the requirements of application, application requirements, equipment convenience and equipment cost reduction, and adopt new materials, special materials, or change product structure, or improve process requirements, or will be different. Variety of products are produced in combination.
